Proposal for `WrapMode: 0` using `text-wrap: balanced`

[kmamal]

We were hoping to get support for WrapMode: 0 working in our app and we found the following: In css4 there is property called text-wrap. When it is set to balance it works like WrapMode: 0 (https://drafts.csswg.org/css-text-4/#text-wrap). Sadly no browsers currently support this property, but there is a polyfill: https://github.com/adobe/balance-text

What we propose is the following:

• You could add the polyfill to your library and get WrapMode: 0 working.
• If you are hesitant about adding the polyfill, you could simply add the text-wrap: balance property when WrapMode: 0 is set. This should have no negative side-effects right now and is something you'll probably to do anyway once browser implementations start arriving. Then we can add the polyfill on our side and get it working now.
